I still hang out to my Sims 2 Store Edition, because this is a way for me to start my game without using my M&G CD, and I guess a way to bypass noCD stuff.
When I create a lot and package it to a file and click on the LotSegment, at the bottom, the version says : The Sims 2 Store Edition.
The only lot I ever uploaded was in 2009 at TSR.
I redownloaded it, and the version says : Mansion & Garden.

I take that the version of a lot determine if one can use it or not.
I went ahead and installed my old lot without a problem, or without any error message.
Now I wonder if it would work the other way around?
Can someone on the UC or on discs up to M&G, be able to install my lots?(Store Edition version)
If someone wants to try, you are welcome to ask me, and if this was the wrong forum to post redirect me.

I would need one member on UC and one member with discs up to AL/M&G to try and install a lot of mine using Clean Installer.
I am curious, again.

EDIT:
I am adding a link to my SFS, a zip that contains a packaged Lot I just created. This is a empty residential lot.
Do not attempt to install it if you do not have Mansion & Garden.
I would advise to rename your EAGames folder (in your Documents)and start your game, so a new empty one is created.
Then use Clean Installer to install my test Lot.http://simfileshare.net/download/443795/
The only difference will be the version, see picture attached.

Thank you @HugeLunatic
But you won't have to search high to find one, as I am editing my post to share one for people to try.
Where do you see EP99 on lots?(in SimPE of course) I cannot see this/don't know where to look.

Yay!
Thank you gdayars. Yep, it says Store edition in the version in SimPE, that I knew. It was the EP99 thing I could not find.
So I guess Rosie can start sharing her Lots on here. Not that she wants to, but she could.
Thank you again so much for testing this for me.
